Siemens 331-3001 Damper Actuator Pneumatic No.4 Universal Kit 3-13 PSI

Siemens 331-3001 Damper Actuator Pneumatic No.4 Universal Kit is a high performance pneumatic actuator for controlling air dampers in HVAC systems. The airflow control in this model is within a spring range of 3 to 13 PSI, allowing precise control over airflow. The actuator has a 4" stroke and mounts to an extended shaft to accommodate a variety of damper sizes and configurations. The working of this actuator is based on the conversion of pneumatic pressure into mechanical motion. The actuator’s damper position is adjusted by the diaphragm and spring mechanism to vary the control pressure and optimize airflow and maintain desired environmental conditions when the control pressure varies. The universal design allows its usage in HVAC systems commercial and industrial such as ventilation, heating and air conditioning.
